Method and Apparatus for Detecting Individual Fiber Breakage in Multi-Fiber Optic Cables.

Abstract

The patent application concerns a method and apparatus for detecting and assessing the light transmitting integrity of the individual fibers in a multi-fiber optic cable bundle. This is achieved by edge illuminating the bared fiber ends at an input terminal cable end, and detecting the quality of transmitted light emanating from the bared ends of the fibers at a receiving terminal cable end. The transmitted light emitting from the face of the receiving cable end is magnified by a microscope or the like. A second light source illuminates the surface of the receiving cable end to enable the faces of the broken fibers to be distinguishable from the remaining background. A suitable camera attachment may be provided in conjunction with the microscope to obtain a permanent record of the magnified image of the output cable end.
